Answer:
True.
Explanation:
In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.
Basically, the normal blood pH of a human being should be between 7.35 and 7.45.
Hence, one of the ways in which the body regulates blood pH is with proteins by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.
A protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.
Hence, the substance that makes the blood red is an iron containing protein known as hemoglobin.
Answer:
I do not understand your question
Ahem, well the audience will be towards kids. Kids love pets, we know they love pets, who doesn't love pets. You know what they love the most? Puppies. & Do you know who they bug about getting a puppy? Their parent. You target the children, that's who your audience is. Now for the two paragraphs...(maybe)
Dogs, I believe are an essential part of a human's life. They can bring comfort, protection, happiness into one's life. They can be used for jobs. What kind of jobs you're asking yourself, well you've asking the wrong person. Ask me instead, they can be used as a service dog, they can get the sheep together, they can even be provided for therapy. Taking care of a dog is a HUGE responsibility and should be taken very seriously. They need to be fed the right type of food. Depending on what type of breed they are of course. They need to be taken on walks, taken to the vet for a check out, cut their nails. They're basically a child, but better.
